Vintage JanSport Aluminum Frame Hiking Backpack

I believe this is a Cascade model from the 1980's or 1990's but I'm not 100% sure about that. Has an aluminum frame, making it very light weight. Backpack is in exceptional condition, it looks like it was only used a handful of times. Comes with matching boot gaiters (which look like they have never been worn), 2 extra straps for securing items to the backpack, as well as the original manual and tools for making adjustments to the frame. The backpack has two main compartments as well as 4 smaller compartments, attachment points for sleeping pad, tent, etc. on the top and bottom. Measurements are as follows: frame height = 38", frame width = 14.5", backpack height = 25", backpack width = 14.5".
